IMPROVEMENT IN ENVELOPES.

Specification forming part of Letters Patent No. 157,487, dated December 8, 1874; application filed October 10, 1874.

To all whom it may concern:

Be it known that I, THOMAS H. BOMAR, of Spartanburg, in the county of Spartanburg and State of South Carolina, have inventedof the party to whom the letter is addressed thereon. Fig. 3 is a perspective view of a return-letter ready for sealing, and showing the part which is torn off. Fig. 4 is a view of the envelope as it is cut out from the paper before folding.

Similar letters of reference indicate corresponding parts.

This envelope is made with two folding sides, A A, one of which, A, is pasted down onto the narrow flaps B B, after they are turned inward onto the central portion 0,

thus forming a pocket for the letter, leavingone of the end flaps, D, ready to be turned over onto the side A, upon which side A is written or printed the name and address of the sender of the letter.

In folding up the envelope containing the letter, the other side, A, is folded down over the loose flap D, and name and address of the sender, and the flap D is turned over onto the back of the central portion 0,.and pasted or sealed, and the letter is addressed as usual, and substantially as seen in Fig. 2.

When the envelope is returned to the writer the addressed portion A] with its flap D is torn off, as seen at E, which still leaves a perfeet envelope, having the name and address of the writer plainly written or printed 011 the outside, substantially as seen in Fig. 1, so that, by turning down the flap D, .and sealin g it, the reply to the letter is returned without the possibility of making a mistake in the name or address of the sender.

The envelope is thus used a second time, which far more than makes up for the additional paper required in its manufacture, besides avoiding all mistakes in the name or address of the writer.

Gr represents perforations on the folding line to facilitate the opening of the envelope.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A return-envelope, having folding sides A A, narrow flaps B B, central portion 0, and end flap D D, and folded substantially as set forth.
